Hola Tomas,
Thanks for reaching out and for your interest in our products 🙂
We have an add-on called Event Tickets Plus that works well with WooCommerce and hopefully it will also work with GoPay as I imagine this Woo integration works at checkout and doesn’t sound it will interfere with what our plugin does. Anyway be sure to check this article going over Woo extenstions compatibility → https://theeventscalendar.com/knowledgebase/compatibility-with-woocommerce-extensions/
Only problem can ocur if Events Calendar creates custome type of product. My question is if it does ?
We don’t create any product related post-types, if this is what you mean.
Summing up I guess the only way to see if everything works as expected is to try it out. While we don’t have a trial period, you can go ahead and purchase the products for testing. If you decide they are not what you are looking for, you can ask for a full refund within 30 days of purchase. For more information take a look at our refund policy.
Please let me know if there’s anything else I can do for you,
Best,
Nico
